Application May 24, 1941, Serial No. 395,007

3 Claims.

The present invention relates to covers for rolls and specifically the rolls of ironing machines.

In the usual ironing machine and in other devices having cloth covered rolls, it is customary to afiix to the rolls, which are usually constructed of metal, a layer of padding niaterial and then to apply one or more layers of a cloth, which may be of canvas or similar material.

These cloth covers are commonly prepared from a strip, whose width is enough wider than the length of the roll to provide for a hem along each side. Into the hems are then threaded cords, serving to tie the cover in place after its application to the roll.

Such covers are applied to the rolls by applying one end of the cover and turning the roll, winding the cover upon it in a spiral of two or more flights, and then tying the cords after drawing as tightly as possible the ends of the cover.

This form of cover is open to several objections, being difiicult to apply without more or less unevenness, and being diflicult to draw together evenly at the roll ends. It also requires considerable excess of cloth to provide for a hem sulficiently generous to allow the cord to function.

Another characteristic of the string tied cover is creeping and consequent wrinkling of the under layers. Since the cord will, under usage, gradually become somewhat slackened and loose, probably due to stretch, the cover is likewise loosened and the fullness thus allowed causes wrinkles and consequent lack of smoothness.

Among the objects of the present invention, therefore, is a cover that obviates these difiiculties, and in addition one that is easy to apply properly and with even tension lengthwise of the roll.

Another object is a cover that will maintain an even tension lengthwise of and peripherally of the roll and thereby prevent creeping.

Another object is a cover that will be less expensive to produce in that it will use less cloth and allow a cutting down of the number of operations required in production.

Still other objects will readily occur to those skilled in the art upon reference to the following description and the accompanying drawing in which Figure 1 is a plan view of a cover before application to a roll.

Figure 2 is an elevation of a covered roll.

Figure 3 is an end view of a covered roll.

Figure 4 is a partial section of a covered roll; and

Figure 5 is an enlarged detail in perspective of a portion of a cover.

As shown in the drawing, the cover consists of a strip of canvas, or other suitable cloth I0,

of suflicient length to pass around the roll H several times, and of a width equal to a few inches greater than the length of the roll. The excess at the roll ends need be suflicient only to overhang the ends of a short distance, but it is preferred to make the cover width such that its edges, when in place, will be near the roll shaft. This will allow for shrinkage when the cover is washed and also place the elastic member as far as possible from the heated element.

This strip I0 is then by means of a suitable sewing machine provided along its side edges with an elastic cord 12, the cord being sewed to the edge while in a stretched condition, and having its ends spaced from the ends of the strip. While it is not necessary to further secure the cord to the cloth, suitable staples or other means l6 may be used to fix the cord ends.

The cover thus prepared is applied to the roll in the conventional manner while maintaining the cord in stretched condition and as the roll rotates is automatically drawn in smoothly over the roll ends. The end portion of the cloth IDA may be secured at its edges as by means of a suitable metal clip M or other means.

In Figure 4 the cover Ill is shown as having been passed around the roll twice, the metal roll being shown at l IA with a layer of padding l5.

Now having described the invention and the preferred embodiment thereof, it is to be understood that the said invention is to be limited, not by the specific details set forth in the foregoing specification, but only by the scope of the claims which follow:

I claim:

1. A roll cover consisting of a strip of suitable fabric of a sufficient length to pass around said roll a plurality of times and of a width slightly greater than the length of the roll to which it is to be applied, said strip having along its lateral edges elastic members which in their relaxed condition are shorter than the length of fabric to which they are applied, said strip having itsends free.

2. A roll cover consisting of a strip of suitable fabric of a suflicient length to pass around said roll a plurality of times and having along its lateral edges elastic material, the latter being shorter than the length of the strip, whereby to provide a free end for said fabric.

3. A roll cover consisting of a strip of suitable fabric of a sufficient length to pass around said roll a plurality of times and having along each of its lateral edges elastic members which in relaxed condition are shorter than the length of fabric to which they are connected, there being means for fixing the ends of said member against movement relative to the fabric, said strip having its ends free.
